Geothermal Solutions

Geothermal energy development requires a clear understanding of how subsurface rocks behave under high temperature and stress. Our conceptual model focuses on thermal, mechanical, and acoustic responses within geothermal reservoirs. These responses are critical for safe wellbore design, long-term system stability, and effective resource extraction.

MetaRock Laboratories provides high-pressure, high-temperature (HPHT) rock mechanics testing for geothermal applications. Our protocols simulate real reservoir conditions using core samples exposed to thermal and mechanical stresses. These services support geothermal system modeling, material selection, and safe field development.

HPHT Multistage Triaxial Test & Mohr Coulomb

Applies controlled axial and confining stress under high temperature to evaluate rock strength. Used to determine shear failure envelopes and peak strength for safe reservoir operation across multiple temperature stages (35°C, 80°C, 150°C).

Thermal Stress Measurement Test

Tracks thermal expansion and stress redistribution as temperature cycles over time. Used to assess stress-induced deformation, crack propagation, and rock integrity in geothermal environments.

Thermal Acoustic Measurement Test

Measures how acoustic wave velocity and rock stiffness change with increasing temperature. Supports evaluation of elastic behavior, thermal damage, and material evolution during heating — including detection of elastic recrystallization.
